In certain circumstances, the computer goes into standby mode automatically: v If a "suspend time" has been set on the timer, and the user does not do any operation with the keyboard, the TrackPoint, the hard disk, the parallel connector, or the diskette drive within the time set. v If the battery indicator blinks orange, indicating that the battery power is low. (Alternatively, if Hibernate when battery becomes low has been selected in the "Power Management Properties" window, the computer goes into hibernation mode.) Note: Even if you don't set the low-battery alarm, the charge indicator lets you know that the battery is low, and then the computer enters the power-saving mode automatically. This default low-battery behavior is independent of the operating system; so if you have set the low-battery alarm, the computer may not do what you specified. It chooses either your setting or the default setting, whichever is appropriate. Any one of the following events causes the computer to resume operation from standby mode: v The Fn key is pressed. v The LCD cover is opened. v The ring indicator (RI) is signaled by a serial device or a PC Card device. v The power switch is turned on. v The resume timer is set. In Windows which has the Scheduled Tasks, the Scheduled Tasks setting has priority over the setting in IBM BIOS Setup Utility. Note: The computer does not accept any input immediately after it enters suspend mode. Wait a few seconds before taking any action to reenter operation mode. Hibernation mode: Note for Windows NT If you are using Windows NT in the default format, NTFS, you cannot create a hibernation file. If you want to use hibernation mode, you will need to reinstall Windows NT with FAT format. In hibernation mode, the following occurs: General descriptions 25
